Feasibility of using a personal digital assistant to self-monitor diet and fluid intake: a pilot study

The feasibility of using an electronic device to self-monitor diet and fluid intake was assessed using the treatment implementation model. The three patients on hemodialysis who participated in this pilot study were asked to self-monitor diet and fluid intake for 12 weeks with a personal digital assistant. The intervention was delivered as intended; however, participants reported problems with usability, and compliance to self-monitoring was lower than desirable. Further adjustments to the intervention will be made before testing efficacy.
